Is there a way to make a vertical line in the js graph library dygraph? I am loading data and would like to put vertical lines like graphite does to show events is there some special context to add vertical lines You've probably figured this out by now, or stopped caring, but the way to do this is with a custom underlay (see http://dygraphs.com/tests/highlighted-region.html and http://dygraphs.com/tests/underlay-callback.html for examples). You provide an underlayCallback function when creating the graph, and it gets called with the canvas element, area (which helps with coordinate math), and

I have a graph that displays a device's power output over time and I'd like to format the legend so that it displays the timestamps in the style of where the current user is (for example, in the US it would show MM/DD/YY h:m:s am/pm , and in EU would show DD/MM/YYYY HH:MM:SS , etc.). Currently, it's set at default, as follows: I pass in a JS Date() object for the x-axis and I've found that you can modify the x-axis labels , but I can't find any info on changing the format of the legend when hovering over the graph. You've discovered the axisLabelFormatter option, which lets you control

In my app I'm displaying 10 charts (charts are from dygraphs .) to monitor data. For displaying charts I'm getting data from my sever by sending ajax request to 4 servlets on every 5 seconds. After 10-15 mins (don't know exact time.) my browser crashes saying "aw!! snap." What could be the reason? Is it javascript that is causing it? or is it because I'm sending request every 5 seconds? Browser tested: Firefox and Chorme. Note:- When I refresh the browser after crash it again works fine for 10-15 mins. JS code: var i=0; var loc = new String(); var conn = new String(); var heapUsage = new

Following the conversation here , is there a way to organize the output dygraphs in a grid? To Have one or more graph in a row. The code below would generate 4 dygraphs arranged vertically. Is there a way to organize them in a 4x4 grid? I tried using tags$div but it wraps all the graphs in one div. Is there a way to apply a CSS property such as display: inline-block; to each dygraph widget? or any other better method? ```{r} library(dygraphs) library(htmltools) makeGraphs = function(i){ dygraph(lungDeaths[, i], width = 300, height = 300, group = "lung-deaths")%>% dyOptions(strokeWidth = 3) %>%

I've been looking into ways to update a plot within an R Shiny application without having to re-render the whole plot. I'm working with temporal data which is animated via a Slider Input ( animationOptions(playButton = TRUE) ). The idea is to somehow highlight the part of the plot which is selected via the Slider Input . Re-rendering the whole plot at every animation step would make the whole application uselessly slow. The most elegant solution with ggplot2 would have been, if shiny offered a way to add layers to the ggplot (e.g. + geom line() ) and integrated this layer seamlessly into the
